International Session 25　　Vestibule 2

Background : Chronic Suppurative Otitis Media(CSOM)is a significant and persistent global health issue, contributing to preventable hearing loss and serious complications, especially in pediatric populations.Children with immunocompromised conditions, such as those living with Human Immunodeficiency Virus(HIV) , are at a substantially higher risk.Objective : To determine the proportion and associated factors of CSOM in children with HIV in Papua.Methods : This hospital-based cross-sectional study involved HIV-infected children aged 1-18 years.Data were collected through medical records and interviews.Bivariate and multivariate analyses were performed to identify contributing factors.Results : The proportion of CSOM among the study population was 55.6％.In the final multivariate model, three factors were identified as significant independent predictors : malnutrition(Adjusted Odds Ratio [aOR] 25． 3 ; 95％ Confidence Interval [CI] 1． 7-368． 7) , prior diagnosis of Acute Otitis Media(AOM) (aOR 8． 4 ; 95％ CI 1． 4-51． 0) , and high viral load(aOR 5． 1 ; 95％ CI 1． 0-26． 1) .Conclusion : These findings emphasize integrated clinical management through nutritional optimization, early treatment of ear infections, and effective antiretroviral therapy.
